Tencel fabric hi thawmhnaw leh in chhunga bungrua siamnaah te hman a ni nasa hle a, a tui hi a hip lut tha hle a, a soft touch a, environment a tichhe thei bawk. A quality hian standard a tlin theih nan systematic testing process a kalpui a, chungte chu core area pathum: physical properties, chemical safety, leh environmental indicators te a huam a ni.
1. Taksa lam thil neih tehna
A hmasain, puan rawng inang tlang, a chunglam chhiatna leh weft skew te enfiah nan mit hmuh theiha enfiah a ni. Chumi hnuah chuan key physical indicator te chu test a ni a:
1. Strength Test: Tensile testing machine hmangin warp leh weft lam hawia breaking strength tehna a ni a, chu chuan puan a chhe thei lo.
2. Shrinkage Test: Sample te chu standard procedure angin silfai leh vawt a ni a, dimensional change chu teh a ni. Shrinkage hi a tlangpuiin 3% aia tlem emaw, a tlukpui emaw a ni tur a ni.
3. Breathability leh Moisture Absorption: Moisture absorption leh quick-drying property te hi permeability cup method emaw water evaporation rate test hmangin an finfiah thin.
2. Chemical Safety Testing neih a ni ang
Tencel hi naturally regenerated fiber ni mahse, thil tha lo awm leh awm loh screening khauh tak a la nei reng a:
• pH Determination: Puan pH hi tuiah an hnim hnuah test a ni a, mihring vun tan chuan safe range 4.0-7.5 chhungah a tla tur a ni.
• Formaldehyde leh Heavy Metals: Residual levels chu extraction hmangin an zirchiang a, formaldehyde level chu 75mg/kg aia tlem emaw, a tlukpui emaw a nih a ngai a, heavy metal awm zat chu a limit aia hniam a ni.
• Banned Azo Dyes: Gas chromatography hmangin carcinogenic aromatic amines screening hmangin dyeing procedure zawm a nih leh nih loh enfiah thin a ni.
3. Environment leh Functional Verification
Tencel hi thing phun atanga siam a ni a, raw materials te hi a chhunzawm zel theih dan tur lantir nan FSC forest certification emaw EU ECOCERT certification emaw a ngai a ni. Chubakah, antibacterial leh UV laka invenna ang chi functional claim-ah chuan a chhe thei lo tih finfiah nan laboratory testing chak zawk neih a ngai a ni.
Testing process hian a tawpah chuan standardized report a siam a, chu chuan parameter result leh conclusion zawng zawng a huam vek a ni. He testing system khauh tak hian consumer rights a humhim mai bakah Tencel fabrics khawvel pum huapa hmanna tur endorsement sang tak-quality a pe bawk.
